I imagine this has been asked before, but the search results were unpromising.
Is it okay to wear a backpack, a nice one? I travel a lot and have been having shoulder/neck pain, which I think is partly due to the heavy briefcase/portfolio bag I carry around.
Can one ever get away with a backpack in a business setting?
I'm not a businessman, but I think a backpack would look unprofessional. I think a pull-behind would be more appropriate if you have problems with back pain.
